A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weight 200 N and is 3.0 m long. What is the tension in each rope when the 700-N worker stands 1.0 m from one end? Hint: Consider the torques about an axis perpendicular to the page through the left end of the scaffold.

#2) Use Newton's Second Law Analysis to solve the following problem. Two masses, m₁ and m2, are linked by a massless rope suspended over a massless frictionless pulley. M2, when released from rest, starts moving down the ramp with increasing velocity. There is friction on the incline between both masses with friction coefficient μk. Assume the masses are point masses and there is no torques acting on the system. +y +X m₁ Ja B7 m₂ "+" (A) Draw the necessary FBDs for each mass separately with the proper sign conventions. Be careful how many normal forces are there; you must label them separately. You must use the provided coordinate system. (B) Develop an algebraic expression for the acceleration of the masses when they are moving. Your final expression for the acceleration must only contain m₁, m2, g, uk, a, and ß only (of course trig anomic expressions that contain the either angles such as sin(a) cos(B), tan(a) and similar ones are allowed if used correctly). The tension is not an…

7) A light (massless) rod of length L = 1.5 m is freely pivoted at one end. Three forces act as shown in the figure below. The force F3 acts at the midpoint. What is the torque due to each force? Take F1 = 6.90 N, Fz = 4.00 N, F3 = 2.00 N, 0 = 20°, and a = 30° Look at picture draw picture and show all work looking for equations
